The radio and navigation module (A2/56) has various optional possibilities for the CD player mode.

CD mode with single CD drive (optional)

The radio and navigation module (A2/56) has an integrated CD drive as an option (code 818) intended for
playing audio CD's . If the radio and navigation module (A2/56) is equipped with a CD drive for navigation
(Code 357) as an option, it is also possible to play audio CD's . (However, during the navigation mode it is not
possible to play audio CD's Opening the operating and display module "(Open " button) allows access to the
CC slot and CD slot.

CD changer mode (with code 819)

The CD player with changer (A2/6) is actuated by the radio and navigation module (A2/56) .

The control signals and audio data from the CD player with changer (in trunk) (A2/6) are transmitted via the
digital data bus (D2B ). The changer is actuated by pressing the "CD" button twice . (When single CD drive is
installed).

Insert only 12 cm CD's into the CD player with changer (in trunk) (A2/6) , also do not use 8 cm CD

adapter .

On sound system (code 810) the sound amplifier (A2/13) takes over final amplification of the audio signals.

The signals between the radio and navigation module (A2/56) and sound amplifier (A2/13) are transmitted
via the digital data bus (D2B ).

The amplified signals are output by the vehicle loudspeaker system.

If the vehicle is equipped with sound amplifier (A2/13) the radio and navigation module (A2/56) should

be coded correspondingly with STAR diagnosis, otherwise malfunctions can occur when reproducing audio
signals.

When a magazine is inserted in the CD changer it is checked and a table of contents is made up. When the test
is completed the system automatically switches over to the playback mode and starts with the first title or next
possible compact disc.

If the system switches over to the CD mode before the test is completed the system starts playback of the CD
which was presently being checked.

The radio and navigation module (A2/56) offers the following functions in combination with the CD player
with changer (in trunk) (A2/6) and/or single CD drive :



Scan function

When the multifunction " Scan " key is pressed each title on the current CD is played for approx. 8 s .
The function is terminated by pressing the multifunction " Scan " key again.



Title forward/backward

If the "joystick " is pressed to right the next CD title is skipped. Pressing to left within the first 10 s of
playback causes jumping to the previous title, otherwise to the beginning of the title presently being
played. If the" joystick " is held to left or right the changer jumps from one title to the next within short
time intervals without playing them.



Fast forward/rewind (music search)

If the "joystick " is pressed up or down the titles are played quickly. This allows specific parts of a title to
be played or skipped. When the start or end of the CD is reached the search is interrupted.



Title repetition and random playback

Random playback can be activated/deactivated with the multifunction " RDM " key. When activated this
function is indicated on the display and random playback can then be selected. The random playback
feature affects only the CD presently being played back. Title repetition can be activated/ deactivated
with the multifunction " RPT key. The title presently selected is repeated until the function is deactivated.

The random playback and title repetition remain active, even when the radio and navigation module

(A2/56) is switched off and switched back on again. Actuating these two functions simultaneously is not
possible.
